Preheat oven to 350F
Melt the brown sugar, butter, and golden syrup until fluid. Mix in the peanut butter and honey until combined. Add the oats until combined.
Add to a 9 inch round pan (or 9-inch square pan) bake 40-45 minutes or until golden brown.
While the flapjacks cool, melt the chocolate in a microwave on high heat in 30-second intervals until melted.
Once cooled, drizzle the flapjacks with the melted chocolate and leave to set before serving.

Can’t find golden syrup? Use dark corn syrup in its place.
When melting butter and sugar together do this over a low heat. High heat can make it end up hard and taffy-like.
To avoid a greasy flapjack, mix the butter and sugar mixture well until you see no sign of melted butter
When baking, watch closely and remove from the oven when the edges are golden. Overcooking may result in a hard, crunchy flapjack.
For a crisper flapjack, use a more shallow baking pan and bake at a higher temperature.
